Features

USB-C Docking Station Turns Your Device’s USB-C or Thunderbolt 3 Port into a Multiport
Workstation

The U442-DOCK3-B expands the potential of your tablet, laptop, Chromebook, MacBook, smartphone or
PC’s USB-C or Thunderbolt 3 port. It’s ideal for transmitting 4K video and audio to a large display, adding
a thumb drive or other USB peripheral, powering and charging a PD Charging 3.0-compliant mobile
device, connecting to a Gigabit Ethernet network and a lot more—all at the same time.

Supports USB DisplayPort Alternate Mode for Transmitting Audio/Video Signals

With a source device that also supports USB DisplayPort Alt Mode, you can extend video from your
primary display to another, duplicate the same video on both displays, or change the second display to
your primary.

Transmits Crystal-Clear 4K HDMI Video and Digital Audio

To send digital audio and Ultra High Definition video to a 4K-ready HDMI television, projector or monitor,
connect the corresponding port to the display using an HDMI cable (sold separately). The HDMI port
supports UHD video resolutions up to 3840 x 2160 (4K x 2K) at 30 Hz. The VGA port supports high­definition resolutions up to 1920 x 1200, including 1080p, at 60 Hz. You can transmit the same video
signal through the HDMI and VGA ports simultaneously with a maximum resolution of 1080p on both. A
DVI display may be connected to the HDMI port using an HDMI to DVI adapter (sold separately).

Connects Up to 3 USB Peripherals

The two USB-A hub ports and single USB-C data port accept USB peripherals, such as flash drives, mice,
keyboards and printers, and share a maximum 10W (5V 2A) of power. They support fast USB 3.1 Gen 1
data transfer rates up to 5 Gbps and are backward compatible with USB 2.0 and USB 1.1 devices. The
BC 1.2-compliant USB-A port next to the memory card slots provides up to 1.5A of fast-charging power to
mobile devices.

Charges the Connected Device

The USB-C Power Delivery (PD) port provides power and charging to the PD Charging 3.0-compliant
device (such as a MacBook, Chromebook or Android smartphone) the U442-DOCK3-B is connected to.
Connect the device’s AC wall charger to the USB-C PD port, which supports power input up to 100W (20V
